Abstract

Integrated sensing and communication (ISaC) in the terahertz band can efficiently reduce the consumption of hardware and spectrum resources

while improving the transmission data rate and sensing resolution.Firstly

the development status of ISaC

terahertz communication and sensing were briefly introduced.Then

the strategy of waveform design and optimization for ISaC and the receiving signal processing algorithms were presented.As an example

an OFDM ISaC system operating at 97 GHz was experientially demonstrate

and the performance of ranging

speed and communication were all evaluated in the experiment.Finally

the key issues and research directions of future terahertz ISaC development were discussed.
